This invention relates to improvements in pumps. The general object of the inventionis to provide an improved centrifugal pump.

A further object of the invention is to provide a pump including a rotatable liquid container and wherein the force created by the rotation of the liquid container forces liquid out of the container1 and draws additional liquid into the container.

A still further object of the invention is to provide a centrifugal pump wherein the iluid being pumped assists the motive power to operate the pump. l

Other objects and the advantages of this invention will be apparent from the following description taken in connection with the accompanying drawings, wherein:- I

Fig. 6 is an enlarged fragmentary longitudinal section through one ofthe rotor discharge pipes, and

Fig. 7 is an enlarged fragmentary central longitudinal section through the connection between the stand pipe and the rotating pipe of the pump rotor. i

Referring to the drawings by reference characters, I have indicated my improved pump generally at 10. As shown the pump 10 includes a housing 12 which comprises a cylindrical side wall 13, a bottom Wall 14 and a removable cover 15 which is shown as secured to the side walls by bolts 16. 'I'he housing 12 may include supporting legs 17 for suitably mounting it in an operative position.

Communicating with the interior of the housing 12 and extending through the bottom wall 14 thereof, I provide an outlet pipe 18.

Positioned in the housing 12, I provide a pump rotor which is indicated generally at 20. As shown the rotor 20 includes an operating member 21 and a frusto-conical drum 22.

The operating member 21 includes a central hub 23 having a plurality of opposed horizontal cylinders 24 extending radially therefrom. Extending downward from the hub 23, I provide a reduced hub'25which is rotatably positioned in an aperture 26 of an elongated boss 27 integral with `the housing 12. The lower end of the reduced lfrusto-conical drum 22 includes an hub'25 is supported on the inner raceway `of an antifriction bearing 28 which is supported in a casing 29 securedto the under face of the bottom wall 14 by bolts 30.

The hubs 23 and 25 include a central vertical aperture 31 in which a pipe 32 is positioned. The pipe32 is secured to the hubs 23 and` 25 in any desired manner such as by brazing it thereto.`

Extending radially from the hub 23 on top of the cylinders 24, I provide a plurality of ybosses 33, one foreach cylinder. Each of the bosses 33 includes a passageway 34 which communicates with the interior of its associated cylinder through the top wall thereof and each ofthe passageways 34 open into a central aperture 35 provided in the hub 23 which communicates with the interior of the pipe 32.

Extending upwardly from the hub 23, I provide a reduced shaft 36 which extends through `an aperture 37 in the cover 15 and includes a reduced end portion `38 which is mounted in an anti-friction bearing 39. The bearing 39 is shown as positioned in a casing 40 `which isv secured to the cover l5 by bolts 41.

For rotating the shaft 36, I have shown a pulley 42 mounted on the reduced Vportion 38 thereof above the bearing casing 40. This pulley may be driven by a belt fromany suitable source of power. It will be understood however that any suitable means of rotating the shaft 36 may be used. The apertured hub 43 which is mounted on the shaft 36 and secured thereto by a key 44. I i

The outer ends of each of the cylinders 21 are closed by hollow conically shaped caps 45 each of ywhich includes a reduced outlet portion 46. The

caps 45 may be secured to the cylinders 21 in any desired manner such as by threaded engagement therewith as indicatedat 47.

Secured to the outlet portion 46 of each of the caps 45 as by threaded engagement therewith I provide a discharge pipe 49. Each of the discharge pipes 49 extends frornits associated cap 45 upwards in helical formation to the frusto-conical drum 22 and extends around the drum to a position adjacent the top of the drum and approximately 180 degrees from its associated cap 45. The discharge pipes 49 may be 'secured to the drum 22 by brackets 50 or in any other desired manner.

The ends of each of the discharge pipes 49 are preferably provided with a nozzle member 51 which is shown as secured to the pipe by threaded engagement therewith as indicated at 52 in Fig. 6; 'The nozzles 51 each include a conical recess 53, the large end of which communicates with the interior of the pipe 49 and the small end with a reduced aperture 54 provided in the nozzle. A section of the discharge pipes 49 adjacent their nozzle ends are preferably directed outward from the drum 22 as shown in Fig. 4 and are adapted to direct a stream of water towards a plurality of vanes 55 which are integral with the cover 15 and extend downwardly therefrom. i

When the pump 10 is operatively installed in a water well such as indicated at 56 in Fig. 1 the pipe 32 extends downwardly a predetermined distance in an enlarged cement-lined sump 5'7 and is rotatably connected to a stationary pipe 58 by a coupling member 59 as clearly shown in Fig. 7.

As shown the coupling member 59 includes a split casing 60 which is secured together and securely clamped to the pipe 32 by bolts and nuts 6l. The casing 60 extends beyond the lower end of the pipe 32 and surrounds the stationary pipe 58 and includes a plurality of spaced grooves 62 in its inner face in which rings 63 secured to the cuter face of the stationary pipe 58 are positioned. Surrounding the coupling member 59, I provide a tank 64 which is secured to the stationary pipe 58 in Water-tight engagement as at 65.

Extending downwardly from the housing 12 to the tank 64, I provide a pipe 66 which communicates with the interior of the housing 12 and the interior vof the tank 64. The pipe 66 may have a control valve 67 interfaced therein.

Adjacent the lower end of the pipe 32, I provide a check valve 68 which may be of any desired type adapted to allow upward passage of fluid into the pipe 32 and prevent downward passage of fluid out of the pipe 32. The stationary pipe 58 extends downward in the well 56 a predetermined distance below the water level in the well, where it preferably has a section of perforated pipe 69 or screen secured thereto. Adjacent the lower end of the pipe 58, I provide a check valve 70 similar to the check valve 68 of the pipe 32. The check valve 70 may be of any desired type adapted to allow fluid to pass upward into the pipe 58 and prevent fluid from passing downward out of the pipe 58.

To start operation of the pump 10 the pipes 32 and 58 and the cylinders 21 are filled with water, which may be done by removing the cover 15 and iilling the housing 12 with water. Thereafter the cover is replaced and the shaft 36 rotated in a clockwise direction through the medium of any suitable source of power as previously described. As the shaft 36 rotates the drum 22, the operating member 21 and the pipe 32 rotate with it. As the operating member 21 is thus rotated the centrifugal force created by the rotation thereof forces the water in the cylinders 24 outward and into the discharge pipes 49.

The cross section of the cylinders 24 being greater than the cross section of the discharge pipes 49 causes a pressure to be built up in the cylinders which forces the water through the discharge pipes and out through the nozzles 51. Furthermore, by constricting the discharge apertures of the nozzles additional pressure is created in the discharge pipes, which forces the water out of the discharge nozzles at a speed greater than the rotation of the device. As the water is discharged from the nozzles 51 it strikes the vanes and assists to rotate the drum.

As the centrifugal force forces the water out of the cylinders 24 additional water is drawn into the cylinders through the passageways 34 from the aperture 35 which communicates with the interior of the pipe 32. As the water is thus drawn from the pipe 32 additional water is drawn up into the pipe 32 from the pipe 58. After the water discharged from the nozzles 51 strikes the vanes it falls downward in the housing 12 and then flows out of the housing through the outlet pipe 18. When the pump is operating the water level in the housing 12 is approximately at the height indicated by the broken line A in Fig. 3.

To prevent air from leaking into the pipe 32 at the coupling member 59 during operation of the device the valve 67 is opened sufficiently to allow a trickle of water to flow from the housing l2 into the tank 64 and maintain a water level therein at a height indicated by the broken line B in Fig. '1. Thus it will be seen that the rings 63 are completely submerged, and instead of air leaking into the pipes water will be drawn thereinto.

When the pump is not operating the check valve 68 prevents the water in the pipe 32 from leaking out through the coupling member 59 and the check valve 70 prevents the water from flowing out of the pipe 58 back into the well. VThus it will be seen that the device requires to be primed only before its initial operation.

From the foregoing it will be apparentV that the amount of power required to operate the device 10 will be only that required to overcome friction and to rotate the weight of the rotating parts and the weight of the water carried thereby, as there is no back action of the water being pumped, against the motive power.

The pump 10 may be installed in a well without the stationary pipe 58 if desired. When thus installed the rotating pipe 32 is preferably positioned in a suitable well casing.
